Abstract: 167,400. Economical Boiler Washings Co., Ltd., (National Boiler Washing Co.). Aug. 26, 1920. Emptying; washing-out; filling.-In a system for emptying, washing-out, and refilling locomotive boilers, as described in Specification 14840/08, the steam from the separator for the blow-down steam and water is led into a condenser, preferably of the spray type, thereby lowering the pressure in the separator and increasing the quantity of steam separated. Sludge is discharged automatically from the separator at the start and finish of the operations. Water is sprayed into a condenser 9, Fig. 1, into which the steam-pipe 8 from the separator 7 discharges, through a nozzle 21<a>, the supply of water being controlled by a valve 24 operated by a thermostatic element 23 in the condenser. Exhaust steam from, say, the pumps 13, 17 in the filling-water and feed-water pipe lines 2, 3 is condensed in an auxiliary condenser 25, into which is sprayed the feed-water returning through the return-flow pipe 20. The return feed-water may deliver into the nozzle of the main condenser, which may be partly immersed in the water in the feed-tank 19. The valve 35, Fig. 8, in the sludge - diccharge pipe 12 of the separator is operated by a pressure diaphragm 37, to which fluid under pressure is supplied through a pipe 40. A valve 41 in the pipe 40 is opened automatically by a thermal element 51, Fig. 9, which so moves the valve element 46 against the pressure of a spring 49 as to place the inlet port 42 in communication with the outlet port 40. In the closed position, the outlet port is in communication with an exhaust opening 49. The valve 41 is closed at the start and finish of the blowing down of a boiler, springs below the diaphragm maintaining the valve 35 in the open position. In a modification, the valve 41 is operated by a flap in the inlet pipe to the separator. Specification 24768/11 is also referred to.

Abstract: <PICT:0860825/III/1> A multi-stage flash-type evaporator for the evaporation of saline water comprises a series of brine heaters having means for circulating therethrough brine to be evaporated and supplying it to a series of flash chambers arranged to operate at pressure and temperatures which vary from chamber to chamber, the flash chambers operable at higher pressures and temperatures being connected to the brine heaters so as to supply the latter with flashed vapour, while the flash chamber or chambers operable at lower pressures and temperatures are connected for the passage of flashed vapour to one or more condensers provided with means for circulating a cooling liquid therethrough, in which at least one of the brine heaters is connected to a steam boiler so as to receive steam as a heating medium, and means are provided for passing distillate which collects in the brine heaters during operation of the evaporator to a further flash chamber having its own condenser, the arrangement being such that the condensate produced from the vapour flashed off in the further flash chamber has a purity which is higher than that of the distillate and meets the requirements for make-up water for the steam boiler.  In a preferred embodiment the evaporator comprises a series of 5 heaters 10 and 10a through which the liquid to be evaporated is circulated along piping 12 by means of a pump 14.  Heated liquid is then passed to flash chambers 16, whence the vapour passes through pipes 18 into heaters 10 and into 2 condensers 20, which are not circulated by brine but by cooling water which flows along piping 22. Final heater 10a is supplied with steam as a heating medium from a steam boiler 26 through a pipe 28.  Make-up water for the boiler is obtained by re-distilling a small portion of the distillate produced in the evaporator preferably by passing the distillate through a pipe 30 into a flash chamber 32 where it is flashed off and passes through a pipe 34 into a condenser 36. Alternatively the distillate in condensers 20 may be discharged into chamber 32 through a pipe 44.
